Abstract
The invention concerns a durable and good-operability fishing rod which is highly strong and is improved in specific rigidity by preventing excessive resin, reinforced fibers from leaning to one side, and resin pools. The fishing rod has a main layer (,) formed by winding a first prepreg provided by impregnating highly strong fibers with resin so that weight percentage becomes 25% or less so that the fibers are oriented in an axial length direction and a reinforcement layer (,) formed by winding a second prepreg provided by impregnating highly strong fibers with resin so that the fibers are oriented in a direction crossing the fiber orientation of the main layer (,) on at least one side of the inside and outside of the main layer (,). The reinforcement layer (,) is formed thinner than the main layer (,), and resin impregnation percentage of the second prepreg is set to substantially the same as that of the first prepreg.
